1. Distribution of airway narrowing responses across generations and at branching points, assessed in vitro by anatomical optical coherence tomography

    Explore Article Respiratory Research (Jan 23 2010)

    Distribution of airway narrowing responses across generations and at branching points, assessed in vitro by anatomical optical coherence tomography Background Previous histological and imaging studies have shown the presence of variability in the degree of bronchoconstriction of airways sampled at different locations in the lung (i.e., heterogeneity). Heterogeneity can occur at different airway generations and at branching points in the bronchial tree. Whilst heterogeneity has been detected by previous experimental approaches its spatial relationship either within or between airways is unknown. Methods In this study, distribution of airway narrowing ... (Read Full Article)

  3. In vivo 4D imaging of the human lower airway using anatomical optical coherence tomography

    Explore Article SPIE Digital Library (Oct 5 2009)

    Anatomical optical coherence tomography (aOCT) is a long-range, fibre-optic endoscopic imaging modality capable of quantifying the size and shape of the human airway lumen. This paper presents the first application of respiratory gating to 3D aOCT volumetric data. A sequence of time-gated data volumes are generated, characterising the dynamic behaviour of a segment of the lower airway over an averaged respiratory cycle. The technique is demonstrated on in vivo data ... (Read Full Article)
